Someone once told me that my casemate armor was excessive. Something about the poor slub inside not being able to train the mount as it was done manually and the armor was so thick it was to heavy to turn. And I only use 6" normally, your's is 8". I could be wrong, but wouldn't that be heavier? :P

Yes... it's a very light/lightly armed BB, or a heavy/heavily armed AC. Hmmm...battleship....cruiser, battleship...cruiser, battleship...cruiser, battleshipcruiser. Hey I thought you said it wasn't a battlecruiser? ;D

Yes, the secondaries are not thaqt useful against destroyers, due to excessive shields.

That's what I thought.

Too well armoured for an AC.

well it is in responce to all the over guned ACs floating around the world atm  as for the casemate thats wierd I usualy go same as my end/upper armor...

The 3-2 xxx 3 arrangement just seems awkward...why not sacrifice a little armor or speed somewhere else for an extra gun?
